The transport of heat in amorphous materials is largely determined by the behavior of phonons – quasiparticles associated with the collective vibrations of atoms. Researchers have now developed a new way to calculate the heat contribution of phonons using computer simulations. Using the Stampede supercomputer at the Texas Advanced Computing Center, they modeled amorphous silicon – glass – providing new insights into a material that is critical for energy efficiency.
